To all whom it may concern Beit known that l, IRA 0. YVniGHT, a citizen oi! the United Stat/es, residing at Baltimore city, State of Maryland, have invented certain new and useful Improvements in Draft and Bulling Gear for Cars,

-ot' which the following is a specification,

this application being a continuation of my application No4-311,713, tiled lli/lay 25, 19055.

The 4main object of my invention is the provision of a draft and boiling gear for cars wherein the strains and blows of huif- .ing and drawing shall be transmitted to the central stringers or Hoor frame at a plupoints or places, thus distributing the same, over a .large area oli' surface whereby rupture, bending` and injury of the elements constituting the gear and frame will be prevented. Y

il further` object is the provision of a gear which can easily be assembled and quiekl repaired when necessary, and wherein dra t links are, substituted for the yoke.

The invention consists in certain novelties of' consti-notion and combinations and arrangement of parts as hereinafter set forth and claimed.

The .accompanying drawing illustrates an example ofthe physical embodiment of the invention constructed according to one of the best modes l have so far devised for the practical application ol the principle.

Figure 1 is a longitudinal section of Fig. 2. Figi'. 2 is a top plan of the gear as a whole. Fig'. 3 is a cross sect-ion of Fig. 2 on line 8 5-, the straps for supporting the follower blocks being' omit-ted, as they are oit' a well known construction. Figs. l and 5, respectively. show a cheek plate and a draft link. Fig. (i shows the killer block in section taken on line .fn-ra, Fig. 2; l'ig. 7 shows a relatively short key which may be used in lieu of the relatively long front key.

Referring' to the several figures, the numeral 'l designates the center sillsA or stringo ers, in this instance oi steel channel beams with their flanges turned outwardly; .3, the end sill; 3, the two cast metal cheek plates; 4A. the rivets by which the cheek plates are secured to the webs of the channel beams; 5, a slot at the front end of each cheek' plate for receivingr and ,duidingr the end of the key passed through the draw bar; G, an open space in the ri-b partially surrounding slot 5 to allow the passage of the ends of a, short key when such key is used; 7, the front abutinents for block or plate; 8, the rear abutments for the block or late, said abutinents consist, ing of yertica projecting ribs upon the plates and integral therewith; 9, the recess within which the ends of the front follower block moves baokwardly and forwardly; l0, the front abutments for the rear follower block or plate; ll, the rear abutments the rear follower block or'plate; 1:?, the, recess between the two abutments Within which the rear follower block or plate can move; 13, two perforated lugs or flanges at the hot-tom edge of each cheek plate; 14, two metallic straps or plates for supporting and holding the follower blocks or plates in their proper relative positions; 1,5, bolts passed through the holes in the lugs 13 and holes in the ends of the straps; 16, nuts on the bolts; 17, a metallic filler block, at the rear of the rear follower block, having flanges by which it is riveted to the webs of the channel beams, as shown; 18, a recess in the filler block to receive and guide a stem upon the rear follower block; 19, the rear follower block; 0, a stern on the block movable within the recess 18 of the liller block; 21, projecting lugs uponithe face' oi the block which support the helical springs; 22, three project-ing lugs or arms at each vertical edge of the bloeit, the middle lugs at each edge being seated within the rear slots of the draft links; 23, the front follower-bloeit or plate constructed identically like the rear vfollower block 19 and having; a stein 2G seated within a recess at the end of the draw har, two lugs 21, and three lugs or arms 22,' movable within the recess 9, the middle lugs or arms at each side being located within the middle slots of the draft links; 2st, two helical springs supported between the follower blocks or plates; 25, the coupler and draw bar; Q6, a horizontal slot adjacent the rear end of the draw bar; 27, e key in' serted within the slot inV the draw bar end movable therewith; 28, the draft links; 29, the front slot in each link, the same being;1 approximatelyll longer than the width et' the ends of the key whereby the key can move rearwardly without impartingn motion to the links in `bufng; 30, the middle slot in each link which isabout l longer than the width of the middle-lng or arm 22 at the front follower l A .whichslots are loosely seated the middle lugs at the sides or edges of the rear follower bloek or ,platesA The several parts and elements being arm ranged in the relative normal positions sl own by the figures of the drawing, the

' modus operandi" isras follows: Indrawing,

the draw bar moves forwardly, carrying with it 'the key, the two links and rear folw lower block or -plate and compressing the springs, the middle slots of the l'links moving forward relative to the middle vlugs or arms at the sides of the front follower block which bearing againstthe front abut- 26 ments 7 on the cheek plates is stationary.

Vlhen the springs have been compressed the strains not absorbed by -them are transmitted to the channel. beams at sir separate points or places, inasmuch as silnultanee" 1% oosly the ends of the .key strike the forward eindsof the seats, vthe ends of the middle slots in the links engage the middle lugs at the edges of the front follower block or plate, and the lugs 22 at the sides or edges of the rear follower block come into contact with the abutments 10 at the front of the recess l2. In buli'ing, the draw bar, key, and front follower block move rearwardly, the links and rear follower block remaining stationary. When the springs have becomev compressed the remaining strains are trans mitted 'to the channel beams or stringers atseven separate points or l laces, inasmuch as simultaneous! the rear ollower block rests 4o against the il ler block and its edges engage the rear abutment-s 11, l1, the front follower bloek strikes the abutments 8, 8 at the rear of the recess 9, and the edges of the ends of the key are brought into contact 4o with the metall at the rear ends of the SlOS 5 at the fronty ends of the cheek plates. This distribution of the strains both in drawing and buliing after the springs have been compressed, prevents the breaking or 5o bending or other injury of any partor parts of the gear and thus the main end specified as the object of the invention is attained.

I have shown in Figs. 1 and2 a relatively long front key passed through the draw bar,

links, and cheek plates and webs of the sup-A ports, but there may be substituted therefor a relatively short key 100, such as shown by Fig. 7, which will be located entirely between the 'webs of the channel stringere.'
